Our customer made 2 separate cash deposits of $8,000 each at 2 different branches on the same day. One deposit into his personal account and the other deposit into his dba business account. Which "person" goes into section A and which person goes into section B? Which "person" is the multiple and goes on the back?

Here is my understanding of how the CTR would be completed:

PartI, Section A would be completed for each of the two accounts, side 1 for the personal account, side 2 for the business account.
Part I, Section B would be completed for the individual who deposited the funds.
"Person" for the CTR can be a natural person or other, such as a business. I believe the reason this is reportable is because the same individual deposited the funds into the two accounts.
Hope this is helpful.

Yes, thank you very much for a prompt reply!!
